![]() Further, California Buttercup populations are threatened by invasion of alien plants, encroachment by native herbaceous and woody vegetation, potential hybridization, recreational activities, livestock grazing, trampling and habitat conversion. The key factors limiting the recovery and survival of the California Buttercup population in Canada are its specificity to rare maritime meadow habitats, limited dispersal abilities, small area of physical occupancy, and small, highly fragmented populations that constrain genetic diversity. In Canada, California Buttercup is known from four confirmed populations, three recently confirmed to be extant, all occurring along the southeast coast of Vancouver Island. The Canadian population of California Buttercup comprises <1% its global range. It ranges from British Columbia south along the coast to Baja California, but the Canadian population is widely disjunct from the nearest Oregon population. The California Buttercup is a low growing perennial herb with lemon-yellow, flowers (with up to 16 petals), and hairy stems ranging from 15–50 cm tall. The Canadian population of the California Buttercup (Ranunculus californicus Benth.) was assessed as Endangered in 2008 by the Committee on the Status of Endangered Wildlife in Canada ( COSEWIC), and in February 2011 the population was listed as Endangered under Canada’s Species at Risk Act ( SARA) Schedule 1. The recovery of California Buttercup will be coordinated with the recovery of at-risk species inhabiting maritime meadows associated with Garry Oak ecosystems (Parks Canada Agency 2006). Implementation of this strategy is subject to appropriations, priorities, and budgetary constraints of the participating jurisdictions and organizations. This recovery strategy will be followed by one or more action plans that will provide information on recovery measures to be taken by Environment Canada and/or the Parks Canada Agency and other jurisdictions and/or organizations involved in the conservation of the species. ![]() All Canadians are invited to join in supporting and implementing this strategy for the benefit of the California Buttercup and Canadian society as a whole. Success in the recovery of this species depends on the commitment and cooperation of many different constituencies that will be involved in implementing the directions set out in this strategy and will not be achieved by the Parks Canada Agency, or Environment Canada, or any other jurisdiction, alone. It has been prepared in cooperation with Environment Canada, the provincial government of British Columbia, and the Songhees Nation. The Minister of the Environment and the Minister responsible for the Parks Canada Agency is the competent minister for the recovery of the California Buttercup and has prepared this strategy, as per section 37 of SARA. 2002, c.29) ( SARA), the federal competent ministers are responsible for the preparation of recovery strategies for listed Extirpated, Endangered, and Threatened species and are required to report on progress within five years. ![]() The federal, provincial, and territorial government signatories under the Accord for the Protection of Species at Risk (1996) agreed to establish complementary legislation and programs that provide for effective protection of species at risk throughout Canada. ![]()
